The volume of the entire expected crop of strawberries = Workday yield * Number of calendar days * Number of workers
Let's take each statement one by one.
(1) A workday yield is 45 liters.
We do not know 'the volume of the entire expected crop of strawberries,' can't get the value of Number of workers. Insufficient.
(2) The expected crop is 13,500 liters.
We do not know 'the workday yield,' can't get the value of Number of workers. Insufficient.
(1) and (2) together
From The volume of the entire expected crop of strawberries = Workday yield * Number of calendar days * Number of workers, we have
13,500 = 45 * 15 * Number of workers
=> Number of workers = 20. Sufficient.
The correct answer:
C
Hope this helps!
